首先，这是我的用于绘制辐射模式的乳胶代码。
\documentclass[10pt,border=10pt]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{polar}
\pgfplotsset{compat=1.12}
\begin{document}
\begin{tikzpicture}
\begin{polaraxis}[
xticklabel=$\pgfmathprintnumber{\tick}^\circ$,
xtick={0,30,...,330},
ytick={-40,-30,...,0},
ymin=-40, ymax=0,
y coord trafo/.code=\pgfmathparse{#1+40},
rotate=-90,
y coord inv trafo/.code=\pgfmathparse{#1-40},
x dir=reverse,
xticklabel style={anchor=-\tick-90},
yticklabel style={anchor=east, xshift=-4.75cm},
y axis line style={yshift=-4.75cm},
ytick style={yshift=-4.75cm},
legend style={nodes={scale=0.7, transform shape},at={(1,1)},anchor=south west}
]
\legend{On wafer transition, Coaxial connection}
\addplot [no markers, thick, blue] table [x = theta, y=E] {test.txt};
\addplot [no markers, thick, red] table [x = theta, y=E] {coaxial.txt};
\end{polaraxis}
\end{tikzpicture}
\end{document}
它看起来像这样：
我想要实现的目标如下：
在左侧添加 ylabel 并使用 xlabel 作为“-30 -60 -90...”。
文本文件如下：

答案1
您可以在选项中进行计算xticklabel，以便有条件地设置标签。此外，您还可以放置和移动ylabel（即是轴）使用y label style={at={(yticklabel cs:0.5)}, xshift=-5.75cm, anchor=east}左侧的刻度是轴。
